Chaldene , also known as ', is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaiʻi led by Scott S. Sheppard, in 2000, and given the temporary designation '.
Chaldene is a small moon orbiting Jupiter that travels backward relative to Jupiter's rotation, and it was discovered in 2000 by astronomers at the University of Hawaiʻi. Because of its irregular orbit and small size, it's part of a group of lesser-known Jovian moons that help scientists understand the history and composition of Jupiter's satellite system.
